- Mizuno JPX923 Forged vs Srixon ZX5 MKII Performance and Forgiveness are put head to head of these very popular irons. Both aimed at very similar golfers but they do things slightly differently. Also one is more forgiving from certain areas of the face when miss hit than the other. Which one wins for you. In Part 1 we look at the Aesthetics, Feel and Performance into a Green. In Part 2 of this video we look at the Overall Performance differences in Ball Speed, Peak Height, Control into the Green etc and the ALL IMPORTANT Forgiveness in Strike differences between the two Irons.

I got fitted a week ago and tried both these irons along with ping, big bertha, paradym and a few others, as well as a plethora of shaft combinations. The shaft made a huge difference depending on the iron I was using. I ended up with a very light weight steel shaft and the ZX5 MKIIs which gave me more height and 15 yards more distance compared to my current irons even though I was swinging the ZX5s 1-2 mph slower. Some other club heads gave me almost the same distance results, however not as consistent as the ZX5s though so I ended up going with them and I can't wait to try them on the golf course!
Love your review format !! So much info .. this is great to backup personal testing before purchase! You are my most recommended channel .. people appreciate the comprehensive work !!
thank you so much for this wonderful review....these are the 2 clubs i had narrowed down to . knowing my fade i usually hit off the toe so great info !!
Really glad you enjoyed the video 👍🏻 👍🏻
I got the Mizuno JPX923 Forged irons about 6 months ago after being a Ping guy for 45 years. Pretty sure I won’t be going back to Ping again. I absolutely love the Mizuno’s.
Same here ! I won't look back.
Thanks Jay for this excellent and meaningful review (swinging at a "typical" speed for most of the JPX line users). I have experienced how close the performance and forgiveness of the JPX923 Forged and ZX5 Mk II really are.
I'm just back from my first ever fitting sessions with Mizuno and Srixon. All I can say is that I regret never having done that before; the sessions were a lot of fun and revealing (the figures do not lie)! Mizuno's Swing DNA also confirmed that my two favourite shafts were amongst the 3 recommended ones (I opted for the SteelFiber 95i).
The two clubs that bubbled up to the top were the ZX5 Mk II and - to my surprise - the JPX923 Forged. I absolutely loved the way they both felt and performed. The only problem is that I am not a big fan of the look of the JPX line compared to the Mizuno Pro models. So I was hoping I'd get roughly the same performance out of the Pro 243 or at least the 245 but to me, neither felt as generous or forgiving as the JPX Forged or the ZX5.
In the end, my choice went to Srixon, for performance, feel and blending capabilities. ZX5 for the mid irons (7-5i), a ZX Utility 3 20° (instead of a 4 iron in ZX4), and ZX7 from PW-8i. The ZX7 blend better with my Cleveland wedges. I cannot wait to get my new clubs.
Good info.
Thanks, nice video as usual. Unless I missed it, I would like to have seem the dispersion comparison between both sets of clubs because on other tests the 923s have performed really well. It would also be interesting to see the ZX4 compared to the 923 as I suspect the 923 fits in between the ZX5 and ZX4. If, an when, I get a new fitting the ZX4 will definitely be my go-to choice along with a couple of other so-called game improvement irons. I currently play the JPX919s but looking for something different.
My last fitting involved the Jpx 923 forged, 225 pro, ZX5 MK II, ZX7 MKII, TM 790, TM 760 and the Cobra forged Tec. My fitter didn’t allow me to look at the clubs so it was somewhat blind. When the fitter asked which one felt best I mentioned #1 & #5, turns out that #1 were the ZX5 and #5 were the ZX7. They feel amazing, nothing compares unless you want to purchase a set of Miura’s. I ended up with a blended bag consisting of a ZX MK II utility 3 iron, ZX5 MK II for irons 4-6 (bent back a degree each) and ZX7 MK II for 7-PW. I totally agree with @ariasfit comments, I got my clubs in under two weeks. My best friend is a scratch golfer who only plays Mizuno clubs, he asked to try my clubs and he is sold, he is purchasing a full set of ZX7 irons. The hype is real!
Srixon irons are every bit as good as every other brand for sure and they deserve more attention for what they do. Yeah ok being honest, is the custom fitting (stock no upcharge) selections as comprehensive as Mizuno, absolutely not and also are there the same amount of heads to choose from with specific uses as Mizuno, no also, but for the irons they do make, they just perform really really well and more golfers should spend the time to try them at least 👍
How's the utility iron?? Also, your 4-6 set you "bent" back, is that +1 when ordering tgem??
@@gcoffey223 I love the utility iron, better than my previous cobra radspeed hybrid., buttery smooth and incredible feel. I have had an issue with the ust coil shaft and they replaced the iron. Excellent customer service. My ZX5 4,5 and 6 iron are bent 1° weak each. My utility, and ZX7 irons are normal degree angles from Srixon. I have a ust coil stiff shaft on the utility and project x 6.5 rifle shafts. I absolutely love my set of Srixon irons, you can’t go wrong with them!
@jaredfofonoff7615 ha ha ha... I got that rad speed cobra hybrid too!! I think that 3 iron in a recoil f3 would be perfect. I tried all the shafts getting fitted(still haven't pulled the trigger due to holidays) but those zx5 snd 7's felt amazing and those shafts fit me the best. Thank you for the input, may you find the fairway!!
Great video. I bought both sets earlier in the summer to compare them and had the same specs and shafts in both which meant weakening the lofts in the 923 by a degree. For me the ZX5 is significantly better and I still have those and I returned the 923's. The turf interaction was much better with the ZX5 and the 923's had a tendency to dig. I also saw poor strikes with the 923 hook way left and that never happens with the ZX5 and I can't explain why. Overall for me the ZX5's have a higher ball flight, go straighter, are more forgiving, and have better turf interaction. The distances for both were very similar.
Hi Derek, thanks for your individual opinion on how you found these two irons, golfers are unique in themselves and find different things so really glad you found the right set for you 👍🏻
The V sole is the reason I got the ZX7 MKII and it's the reason the ZX5 MKII irons have such good turf interaction.
How’ out reaching out to Richard Kempton and having some of these clubs measured with a Golf Mechanix MOI measurements….which is a dynamic swinging ‘SW’ of sorts…basically length squared x mass in grams. While you believe you are shaft ‘agnostic’, think a deeper ‘club assembly’ measurement might shed additional light on your excellent club hitting comparisons…
Another thorough review, thanks. Have you tested the Srixon ZX5 mk ii vs. the Ping i230?
Haven't done that one yet Dan but I can get it on the list for you 👍🏻
Thanks@@AskGolfNut
Hi Jake, thanks for the reply - didn't mean to question your integrity - I can see that you were scrupulously fair in your testing and comments - of course wear whatever you like - it's just some advice on the optics when you are doing a head to head comparison - like the ref in a football match wearing one of the team's scarfs LOL . BTW, it is great that you hit 50+ balls with each club - most tests are not so thorough.
All best, Andrew
Hi Andrew, that's ok I wasn't suggesting you were questioning it, it's just a bit more background for my testing habits and rituals so other viewers watching know how the data is measured 👍🏻
I'm doing a live stream on Monday (3rd June) at 7pm UK Time.
If you have any other questions or queries, feel free to join in and I can answer them live for you 👍🏻 👍🏻
Great review thanks. Test looked completely fair and comments impartial but unusual for a reviewer to be wearing branded cap and shirt of one of the tested clubs.
Hi Andrew, thanks for the comment. I have my own preferences for the brand of clothes etc that I may choose to wear personally, but it doesn't stop me from being unbiased and fair from reviewing any particular piece of equipment. The biggest plus point for any findings is that it is done with the use of GCQuad which doesn't care which golf club in using it just gives club head and ball data for each. The biggest reason why I'm so analytical and why I give club head data is that numbers don't care about bias, so it's always a fair test 👍🏻👍🏻
quick question... do you think the v teck sole in the srixon works or is it just good marketing?
Would love to see a comparison of the zx5 vs new T200
Still trying to get through to Titleist about getting hold of them to test 😟😟
Great vid, Jay
I'm not sure if you've noticed, but at 06:55 when you compare the heel strikes, it looks like you've actually mixed up the zx5 and forged data.
You had the zx5 data on the screen when talking about the forged and vice versa. The jpx forged had 1.36 efficiency and the zx5 1.34, not the other way.
Not sure if that would change your overall conclusion of their forgiveness, but it basically means that the forged won both out of the heel and the toe.
Yep this has been picked up previously, I'll copy and paste my response as that hopefully will adequately answer your questions 👍
Hi Tom, Thanks for the heads up on this. Looking back at it again the information I collate is done by multiple screenshots from FSX and then placed within the editing timeline, so to try and help as I've made this confusing........ My words are correct, its the slide titles that are wrong. I've used the slide titles the wrong way round 🙈 Well Done for spotting this, you are the only one to so far 🙂
So to reiterate, listen to what I say on the heel hits rather than the on screen stuff 👍 when i film I record directly after filming and am reading it straight from FSX2020 analytics and then do the editing stuff afterwards.... of which i messed up... Every one is human i guess 😀😂
The 923 Forged did well being that its a 1 piece vs hollow Zx5. Nice review.
Zx5 is not hollow. That’s the zx4.
the zx5 and zx4 are hollow. the zx7 are the one piece
Wrong. Srixon describes the ZX5's as: "These cavity back, players distance Irons combine premium forged feel with advanced distance technology. Featuring a narrow topline with moderate sole width, blade length and offset." @@timmy2pillows
@@MXJEFF94 not sure where it says that they are one piece in your quote. The face can be forged but that doesnt mean it is one piece
If I recall correctly the ZX4s and 5s are described as having a mainframe in the back of the club. So is that hollow or cavity back or what?
Another great review as always, im considering the T150, 923 forged or the ZX5/7, im off 7 swing about 82mph for a 7 iron, which have you found to be the best all rounder from those 3? Cheers
I’d also be interested in how the t150 stacks up against the zx5 in forgiveness. I know the zx5 is bigger, but does all that tungsten make the t150 closer in forgiveness than its appearance would make you believe?
If it helps you I have t150s and looking to go to zx5. The 150s are razor thin and very hard to hit unless you are a low handicap
I'd LOVE to see you do a video using ONE club with 4 different shafts, in stiff vs regular, to show how much of a difference a shaft makes. Saying you're exempt from the laws of physics is pretty daft LOL.
I've done a few on my channel over the years. One reaching back many moons ago, and one fairly recently. They are on my channel for all to see. All with open and transparent information.
It proves that I'm not defying the laws of physics. If a golfer pulls in a direction (angle 90 degrees to motion for full bending) or anything other than the direction of travel or 180 to it, the shaft bends. I, in transition pull the shaft along its axis rather than pulling the handle at an angle and therefore creating loading. I have seen a hand full of amateur golfers over the years that also demonstrate a similar characteristic.
They are freely available on my channel for all to see 👍🏻
I hit both in a recent fitting. Personally I felt like the zx5 felt much nicer and did't have that click sound. Mizuno's spin a little more but Srixon launch higher. I got better numbers with Srixon and you can't go wrong with their custom options. They have a little more than Mizuno and you don't have to wait 6 weeks for the clubs. Only waited 10 days.
Sorry but Mizuno custom options are much better. They have a larger shaft and grip selection that doesn’t add any extra to the build. Mizuno also has their shaft optimizer you can try at most local fitters to help determine specs.
@@MrMatthew262 well it’s hard to tell considering it’s impossible to see those options or order without going through a custom fitter. I prefer to order through a website
Hopefully the Shaft Optimiser is used at ALL Mizuno Fitting Centres, as it really is such an amazing tool which cuts through the old 'Bumper Car' style fitting technique employed through the passage of time. Really cuts down the errors and the time within shaft fitting 👍🏻
Just wondering if conclusion on of the heel forgiveness is correct...at least slides show JPX club while you are commenting ZX5... 🤔 Would be good to know what is correct: slides or commentary? Thanks! Tom

Great, thanks!
At 8 minutes you are saying the srixon is better out of the heel but the software is showing the jpx923 (when you are referring to the srixon)
Yes it was a screenshot editing mistake, the labels are wrong so ignore what the label says on the screen for that particular one. Well done for noticing though, proves you were paying attention 😊😊👍🏻
You really like comparing the JPX forged. Think it’s a standard bearer in the category?
Hi Matt, nope just working my way through the list of requests that you guys ask of me 👍🏻👍🏻👍🏻
What do you recommend for a player with average consistency but fast swing? I use to use p790s but my consistency in length was terrible (usually way too long) and switched to Mizuno pro 225s and it’s much better. Do you have a different iron that would be worth looking at? Something that’s forgiving but doesn’t assist in distance?
Pro 223, i230, Cobra Tour to name a few that could work quite well 👍🏻
do you agree with "mygolfspys" rating of jpx923forged being 10th overall in the players distance category for 2023 ?
To be honest I haven't looked at the article to see how and what metrics were used for the test and how it was tested and how the parameters were measured and set. I guess depending on what metrics one is measuring any club could come off better or worse than another 👍🙂👍
I've just searched for the website article and I'm finding myself literally shaking my head as I'm scanning through it..... SOOOOO many holes in the information given its not even funny. For literally every single golf club listed on that test regardless of manufacturer I would take absolutely no notice of it whatsoever. There isn't a hint of how the test is actually conducted and measured and even on the first distance front, no mention is made that golf clubs with stronger lofts are winning the distance chart...... well that's what happens when a club with 30 degrees of loft goes up against the same numbered iron with 27 😂😀😂😂
thank you so much for your response.... !! by the way love your reviews so much info....well done helping us choose !!!
I'm seeing minimal differences no matter where or how , so the average golfer (count me in that group) isn't going to notice the difference. Here in Australia the Mizuno's are around 1/3 more expensive than the Srixon's so that dropped them off my list. Like them both, but the wallet won in the end.
If you want to assess the statistical difference between two sample means, you need to use the standard errors of the mean and not the standard deviation of the distribution (which is what you used). Wikipedia will show you exactly what you need to do (it’s very simple). In this case, based on the number of shots you reported, the mizuno’s spin was statistically different than that of the srixon.
Very happy to be educated in a better way to show the data (although Foresight only show SD and Mean). If you could explain in a dead simple way so I can get where you are coming from and the potential differences between what is currently shown to that of the new way 👍🏻👍🏻
If it's easier / better and would be easily introduced into my content with the restrictions of the software I use then I'm all for it 👍🏻👍🏻
@@AskGolfNut if you want to know whether two sample means are statistically different from each other, you need to calculate the following: (mean_1 - mean_2)/(square root(Std_1^2/n_1 + Std_2^2/n_2)) - btw - a^2 = a*a, so, std_1^2=std_1*std_1 and same for std_2. If the value you get is between -2 and 2, you can be confident that the two means are not statistically different, if this ratio is either smaller than -2 or bigger than 2, then you can conclude that the two means are statistically different). From Foresight you get all the parameters/values you need to calculate this ratio - mean_1 and mean_2 would be the average spin rates in the mizuno and srixon, respectively, the std_1 and std_2, are the standard deviations of the spin rates for mizuno and srixon. Finally, n_1 and n_2 are the number of shots you hit to get the mean and standard deviations for mizuno and srixon, respectively. Foresight gives you all these values, it's just a matter of doing some (basic) algebra. In this example, assuming you hit 50 shots with each club, (5044-4831)/sqrt(331^2/50+364^2/50)=213/69.58=3.06>2 - > The Mizuno spin rate is statistically higher than that of the Srixon. BTW - kudos to you for asking how to do this, because Mark Crossfield makes a similar mistake to the one you made (mixing the standard deviation of the distribution with that of the mean), and despite me pointing it out multiple times he never asked how to do it better. The more shots you hit, the easier it is to distinguish two clubs along the dimensions of interest by having into account sample variability (human testing is the main source, but this also happens with robot testing - with robot testing you just need fewer shots to be able to separate two means).
@danieldias4073 mark is a very interesting individual, giving credit where its due, he is the reason I started my TH-cam channel all those years ago to try and be better and more transparent than the rest (Mark although could be more interactive, I believe he is also of a similar mindset).
Could the above be put into a very simple excel spreadsheet so that the information could be exported and calculated automatically for me given the number of copied and pasted entries from a comma separated value export from FSX? Using =CountA to collect the number of shots for the formula above?
That's me saying, if you have the time and inclination, could it be something that you clearly have far more competence than I to produce effectively also in an efficient way? 👍🏻 👍🏻
@@AskGolfNut yes, you can use an excel formula to calculate/test the difference between two averages. The formula is "T.TEST" and the inputs are the arrays with the values for the two clubs (say, the individual spin rate for each shot hit with the mizuno and the spin rate of each shot hit with the srixon) and then you need to choose the number of tails of the test (2 - this allows to say whether the means are different; if you choose 1 - you will be able to say if one is smaller than the other) and the type of test (3, so that variances are not assumed equal) - this is the formula =T.TEST(array containing club 1 values, array containing club 2 values, 2, 3). The output of this function is going to be a number between 0 and 1 (in this case a probability), and if this number is smaller than 0.05 you conclude that the means are statistically different, where as if the number if larger than 0.05, you conclude that there is not statistical evidence that the two means are different. Note that the number of shots with each club does not need to be the same. I personally think that using this type of methodology really allows to say if one club (say driver) is longer than the other, spinier, more efficient, etc. For club fitting this may not be very useful because 1) player being fitted will likely not be very precise on average and 2) you would need many shots, but when you are trying to say something about the attributes of a club or golf ball (mygolfspy's ball distance analysis is useful and interesting, but they don't realize how much of those differences may simply be due to sampling error, therefore irrelevant - when they wrote about yellow vs white balls, that was really silly) relative to other club this is how it should be done.
@danieldias4073 thanks for the info, I'd lying if I said I understand all that you have written, I do feel that I would need to further understand the whole meaning and context of what you've said to be able to confidently either perform the analysis and also talk about it in a way that I can put it across in somewhat of an understandable fashion 👍🏻
if your not going to say which one you prefer, then y even make such a video?
To show people what the differences are, the strengths and weaknesses, the forgiveness and performance..... All that individual golfers need to attribute to their own game. How does me saying which one I prefer, which has no basis whatsoever to the person viewing, make one better than the other 🤷
The whole idea of a review should be to try and keep subjective preference out of the equation as that changes with the human on the end of the club. The objective differences always win through as its the physical differences between the two products in question.
Thanks for the comment and for watching 👍🏻
